Application filed March 4, 1918. Serial No. 220,362.

To all whom t may concern.'

Be it known that I, SAMUEL REIFF, a

citizen of the United States, and resident of quantity will cause stiffening of the leather upper and also materially add to the thickness thereof. Most machines at present in use tend to add a too great thickness of paste; therefore the principal object of the present invention is to evenly distribute a relatively small amount of cement at predetermined intervals.

An additional object is to provide a sim- Aply constructed highly efficient machine of this nature which can be inexpensively manufactured and operated. Owing to the siinple Y construction of the machine the parts Vthereof are readily disassembled for cleaning, repairing and the like.

The invention resides in certain novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

In the accompanying drawings Figure 1 represents a vertical cross sectional view of a paste applying machine constructed in accordance with my invention, said section being taken on the plane of the line 1-1 of Fig. 2.

Fig'. 2 is a plan view of my improved inachine, the intermediate portions thereof bein broken out.

lIiig. 3 is a -longitudinal vertical sectional view on the plane of the line 3-3 of Fig. 1, and

Fig. 4 is a detail sectional view through the attaching portion of-'one end of one of the scraper members. n n

rllie invention consists broadly of a paste receptacle, a plurality of rotatably mounted paste applying rollers, means for revolving the rollers simultaneously in the same direction, and a plurality of scraper members for removing surplus pastefrom the rollers. rIhe paste receptacle portion of the invention ,is-formed fromv a pairy of preferably cast end members 1 and 2, each of which includes an end wall-3, laterally and inwardly extendingattaching flanges 4 and supporting legs ,5, said legs having laterally extendingattachingfeet 6 whereby the device may be secured to a. suitable support. Y l

i From the several Vfigures of the drawings it willffbenoted that theattaching 'flanges 4 extend from the bottom and side edges of thelwalls 3 and have a trough shaped sheet metal body portion 7 secured thereto 'by bolts .or-rivets V8.A One side wall-of the body 7 has its upper edge portion bent inwardlyy as at v.9 to form a guard, which guard is parallel to the bottom of the paste receptacle and substantially coincident lwithfthe upper edges ofthe end walls 3. This portion partially closes the paste receptacle7 but otherwise its top is open.. j Y

. Any desired number of paste applying rollers l0 may be journally mounted in the paste receptacle, theybeing disposed longitudinally thereofv and having their opposite ends journaled in the end members l. Each of the rollers 10 consists of a shaft 11 and a plurality of cylindrical spaced apart paste applying surfaces projecting from said shaft. In the present embodiment of the invention .these pasteapplying surfaces are provided by the perlpheries of a plurality of spacedv collars 12 which arershrunk, keyed or otherwise secured in spaced Aapart relation on the shaft 11. The diameter of the collars is such that the uppermost point in their peripheries extends only slightly above the horizontalplane of the top of the paste receptacle.

The collars 12 are spaced from the ends of the shafts, and the latter are journally mounted in semi-cylindrical bearing seats 13 which are formed integrally with and projecting inwardly from the walls 3 of the paste receptacle. The seats 13 for each shaft are alined, and when said shafts are in operative position they are arranged parallel to each other. The weight of therollers 10 is sufficient to retain the ends of the shafts 11 within the seats 13 without other retaining means.

n The rollers 10 are revolved by the rotation of shaft sections 14, one of each is detach-k ably connected with one end of each of the shafts 11. These shaft sections are jurnaled in bearings formed in 'hollow bosses which extend outwardly from the wall 8 of the end member 1, said bearings being extended through said wall 3 into the seats j 13 vcarried by the same. Said hollow bosses therefrom. Y

15 form elements of stufling boxes with which packing glands 16 cop'erate. f

The shaft sections 14 are retained agamst longitudinal shifting in their bearingsV by,

are adjacent the shaftfsections 14 are transversely grooved and the `inner ends of the latter have transverse tongues projecting Any preferred means-may be employed for rotating the shaft sections and consequently the rollers 10; for instance-a gear 21 is secured to the outer end of each shaft section and `meshed with an idle gear 22. A 4suitable pulley wheel 23 is vconnected With one fof the-idle gears 22 as-shown. Rotation of the pulley will cause vthe rollers 10 to revolve at a -uniform speedand in the same direction.

" Under some 'conditionstoo much paste 'may adhereto the paste applymgsurfaces of theY rollers; -therefore scraper members I iure-employed for removing the surplus. '40 i One of these scraper members is used for each roller 10, and each comprises-a rod 24 which is disposed parallel `to the shafts 11 vand ascraper plate 25. The rod is preferably'flattened as at 26-toreceiveand permit ready attachment of the scraperpl-ate which is'elongated and/flat. f

' In'ordcr that the scraper vplates 2 5 may lbei adjusteditoward or away from the rollers "10, one end of each rod 24 is provided with '50 a socket 27 for engagement over a stud 28,

'.which studs project inwardly from vthe wall of the rods 24. screw threaded andv have wing nuts 31 3 ofthe endmember `1. The opposite wall 3 of the paste receptacle is'provided with open end slots 29 which are alined with the studs 28 and receive the reduced ends 30 These reduced ends are threadedV thereon,said nutsbeing adapted to "clampingly enga'ge the wall 3 to hold the ,rods in iadjusted positions after being rotated to move the plates toward or away "from the rollers.

In Fig. 1 the relative disposition of the scraperuplates with respect to the rollers 10 is evident, and from this figure it will be noted that these plates together with the Yportion 9 close the major part of the open top ofthe paste receptacle. These parts thus aid in preventing dust and other extraneous matters from entering the paste receptacle and also'retard the circulation of vair to the paste and thus prevent rapid evaporation and consequent thickening thereof. The most important feature of myy invention, however, consists in separatingV the paste applying portion of thejrollers into a plurality of relatively narrow contact surfaces; this naturally limits the amountof paste or cement which is gathered bythe fabric shoe lining, or the leather uppers Vas the case may be, as the same is drawn over the rollers Attentionis also directed to the fact that the scraper mem-bers and the rollers may be readily lifted out of the paste receptacle to permit the Llatter to be cleaned, and that the reassembling is j ust as simple as the dismantling.

I claim 1. In a paste applying machine, ya paste receptacle having an open end slot in one wall, a stud on the oppositewall and alined therewith, a rod having a socket in one end to receive said stud, the opposite'end being reduced and disposed inV said slot, a paste applying roller mounted in the receptacle substantially parallel to said rod, means for revolvingsaid roller, and a scraper plate secured to said rod.

2. Ina paste applying machine, a paste receptacle, a substantially semicylindrical seat formed'on each end wall of the recep-k tacle, said seats being extended inwardly rtoward each other and alined, a shaft section journaled in one end wall ofthe receptacle and extending` into one of said seats, a tongue projecting from the inner end of said shaft section, a paste applying roller having its opposite ends cylindrical and disposed in said'seats, one of said ends being transversely grooved to receive said tongue, said tongue andthe grooved end of the roller being retained in connection by the engagement of thel latter in the adjacent seat, and

'means connected-'with the shaft section to revolve the same.

3. In a paste applying machine, a paste receptacle comprising a pair of spaced end members. having upright walls and laterally and inwardly extending attaching flanges projecting from` the bottom and side edges thereof, a trough shaped body having its opposite ends disposed in contact with said flanges and secured thereto, the upper edge portion of one side wall of the body being bent inwardly over the bottom of the latter to form a guard, a plurality of pastek applying rollers having their opposite ends journaled in the walls of the end members, the axes of the rollers being substantially parallel to the'inner edge of said guard, the

outermost points in their peripheries being sure for the top of the paste receptacle tn slightly above the plane of the latter, and prevent a free circulation of air therein.
